Dear all,

Is there any tool (hopefully a matlab tool) that can let us to try different color halftone experiments?

For example if:

layer 1 = 'Brown' color, dot Size '2', angle '45'

layer 2 = 'Cyan' color, dot Size '5', angle '60'

layer 3 = 'Red' color, dot Size '3', angle '20'

What will be the final color obsered by our eyes?

Any suggestion will be very appriciated.

Should each layer be considered completely opaque? So if a Cyan dot covers a pixel that was previously covered by brown, then should the result be just cyan at that location? Or should the layers be partly transparent / transluscent, so that where cyan overlays brown that a color that is a mix of cyan and brown should be rendered? Are you simulating wet inks (colors blend to produce a single color) or dry inks (lower layer is visible only to the extent that the upper layer is transparent) ?

Hi Walter. I tried to make my question clearer in this link

I would appreciate if you could comment on it.

Thank you in advance.

Hi Mustafa,

You can use the MATLAB Image Processing Toolbox which provides a comprehensive set of functions for image processing tasks, including color halftoning. You can use functions like dither, fspecial, and imquantize to apply various halftoning techniques and manipulate color images.

You can also use this Halftoning Toolbox which is a third-party toolbox specifically designed for halftoning experiments in MATLAB. It provides a collection of functions and algorithms for grayscale and color halftoning. You can find more information and download the toolbox from here:

You can search for other halftoning toolboxes on File Exchange, which are suitable for your example.

Thank you for sending the link. It is a very nice toolbox for halftoning in matlab but it doesn't let you try experiment conditions in the way that I described above.
